摘　　要：用能脱除DBT的烟曲霉经再驯化后同时代谢多种复杂有机硫化合物,尤其是4,6-二甲基二苯并噻吩。烟曲霉对低含硫量的油品脱硫效果显著,48 h脱硫率98%以上;对0#柴油的循环脱硫效果显著,96 h脱硫率90.43%。脱硫烟曲霉环境耐受能力强,可直接应用于脱除石油及其产品中的有机硫。Aspergillus fumigatus Fresen. is used in oil desulfurization after the domestication. It can simultaneously metabolize with many complicated organic sulfur compounds, especially with 4,6-dimethyl dibenzothiophene. It has a significant influence on low-sulfur content petroleum products, with which 48 hours＇ desulfurization rate can be more than 98%, and 96 hours＇ desulfufization rate for 0^# diesel oil can be 90.43%. Aspergillus fumigatus Fresen. has strong environmental tolerance, and can be used directly in the desulfurization of untreated petroleum products.
